BACKGROUND
A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60 mph. The problem is
typically diagnosed as a bad torque converter. American Honda investigated the judder and found that the torque
converter was not causing the judder; rather, it was caused by deteriorated transmission fluid. The transmission fluid
deteriorates quicker than expected when it is exposed to intermittent high heat loads under specific driving conditions.
American Honda is working on a software update that will maintain the transmission fluid temperature within the
desirable range under all driving conditions and eliminate the potential for this judder. American Honda will revise this
service bulletin when the software update is available.
Until the software is released, the judder can be fixed by flushing the transmission fluid as indicated in the FLUSH
PROCEDURE. Make sure the customer is aware that this is a temporary fix and he or she will have to return once the
software is available to make sure the transmission judder is resolved.
NOTE: American Honda defines flushing the transmission as draining and filling the transmission with a drive cycle
three times to help make sure the deteriorated fluid is removed. There are other aftermarket flush systems available,
but American Honda does not recommend using them.
TEMPORARY CORRECTIVE ACTION
Take an automatic transmission snapshot, and review the data. For more information about capturing and interpreting
the data, refer to the job aid Torque Converter Clutch Shudder and Vibration and the Tech2Tech® video “Interpreting
Torque Converter Judder Snapshot Data.”
Once it is confirmed that the judder is coming from the torque converter, flush the transmission three times as indicated
in the FLUSH PROCEDURE. This is a temporary fix that does not affect the durability or life span of the torque
converter.
NOTE: There is no need to call Tech Line before undertaking this ATF flush repair.

ATF-DW1. Other aftermarket flush systems are available, but American Honda strongly recommends that
you avoid using them on any Honda vehicles.

on, then let it idle.
2. Position the vehicle on a lift and, turn off the engine.
3. Remove the ATF filler bolt and sealing washer.
4. Raise the vehicle, and make sure it is securely supported.
5. Remove the drain plug, and drain the ATF.
6. Install the drain plug and original washer and torque it to 49 N.m (36 lb-ft).
7. Lower the vehicle and fill the transmission with 3.3 US qts (3.1 L) of ATF-DW1 through the filler hole.
NOTE: Do not use non-Honda ATF because it can affect shift quality.
8. Install the ATF filler bolt and original sealing washer and torque it to 44 N.m (32 lb-ft).
9. Check that the fluid is filled to the proper level.
10. Raise the vehicle, and make sure it is securely supported.
